3550b9313b avr32: add support for ATNGW100 mkII board
This patch adds board support for ATNGW100 mkII. This board is an upgrade of
the ATNGW100 where the difference is an additional 256 MB NAND flash device and
128 MB 32-bit SDRAM instead of the 32 MB 16-bit SDRAM on ATNGW100.

Tested on ATNGW100 mkII, duh (-:

92c548cd35 favr32: improve touchscreen response
The ezLCD+101 board (to which an favr-32 is fitted) has a long,
unshielded, nasty lead between the touch panel and the ads7843 touch
controller.  In order to get satisfactory response then, we need to
employ every noise-reduction trick in the driver's arsenal.  After
extensive fiddling I've found some good settings:

1) We keep vref on all the time to dramatically reduce settling times
(at the cost of a tiny increase in power consumption).

2) Despite 1 the settling time is still non-zero.  500uS is plenty of
time for the signals to settle

3) Despite 1 and 2 there's still a little bit of noise around.  By
setting a pen recheck delay we make the panel feel less touchy and
twitchy.

Someone with more time and patience myself might be able to tune this
numbers further but these settings are now perfectly acceptable for
normal use.

Tested on ezLCD+101 though should only improve response on other ezLCD+/
favr-32 boards too.

dd5e1339e5 avr32: Hammerhead board support
The Hammerhead platform is built around a AVR32 32-bit microcontroller
from Atmel.  It offers versatile peripherals, such as ethernet, usb
device, usb host etc.

The board also incooperates a power supply and is a Power over Ethernet
(PoE) Powered Device (PD).

Additonally, a Cyclone III FPGA from Altera is integrated on the board.
The FPGA is mapped into the 32-bit AVR memory bus. The FPGA offers two
DDR2 SDRAM interfaces, which will cover even the most exceptional need
of memory bandwidth. Together with the onboard video decoder the board
is ready for video processing.

This patch does include the basic support for the fpga device driver,
but not the device driver itself.

a3bee42f05 avr32: Add support for EVKLCD10X addon boards
This patch lets the user enable support for EVKLCD100 and EVKLCD101
(refered to by EVKLCD10X). By enabling EVKLCD10X support the LCD
controller and AC97 controller platform devices are added.

The user can also choose between the EVKLCD100 (QVGA display) and the
EVKLCD101 (VGA display), this is added to automagically select the
correct panel timing and resolution parameters.

Enabling support for EVKLCD10X addon board will cripple the MCI platform
device a bit since they share two GPIO lines (detect and write-protect).
These two lines are disabled when EVKLCD10X is enabled.

The default configurations are based upon ATNGW100, but with added AC97C
and LCDC driver. Virtual terminal is also enabled by default for
EVKLCD10X boards.

Verified on hardware with a NGW100 + EVKLCD100/101.

6b918657b7 atmel-mci: Platform code for supporting multiple mmc slots
Add the necessary platform infrastructure to support multiple mmc/sdcard
slots all at once through a single controller. Currently, the driver
will use the first valid slot it finds and stick with that, but later
patches will add support for switching between several slots on the fly.

Extend the platform data structure with per-slot information: MMC/SDcard
bus width and card detect/write protect pins. This will affect the pin
muxing as well as the capabilities announced to the mmc core.

Note that board code is now required to supply a mci_platform_data
struct to at32_add_device_mci().

Minor cleanups for the MMC/SD support on avr32:

 - Switch over to gpio_is_valid() instead of testing for only
   one designated value.

 - Provide STK1002 platform data for the unlikely case that
   switches are set so first Ethernet controller isn't in use.
   (That's the only way to get card detect and writeprotect
   switch sensing on the STK1000.)

And get rid of one "unused variable" warning.
